Compatibility & Installation Notes
Verify the controller’s compatibility and accessory port before ordering. Check WiFi signal at the cabinet, then follow the LNK2 setup guide and the app instructions for that controller. Remote access needs a working internet connection. Use the supported Rain Bird app and current firmware for the controller; availability of Rain Bird 2.0 and IQ functions varies by controller and platform. A phone using cellular data away from home is different from the required 2.4 GHz WiFi connection at the controller.

Frequently Asked Questions
Can LNK2WIFI connect to 5 GHz WiFi?
No. The module requires a 2.4 GHz WiFi network.
Does the module include an irrigation controller?
No. This listing supplies one LNK2 module for a compatible controller, sold separately.
Does LNK2 work with every ESP-Me controller?
No. ESP-Me compatibility requires units manufactured after November 2, 2016. Check older controllers before ordering.
Can I use the Rain Bird 2.0 app?
LNK2 hardware is required for supported Rain Bird 2.0 connections, but controller, platform and firmware support must also match. The original LNK1 module is not compatible with Rain Bird 2.0.
Why Buy from Big Frog Supply?
LNK2WIFI fits an upgrade where the existing controller is compatible and a 2.4 GHz network reaches the cabinet. The plug-in accessory format avoids replacing the timer, while second-generation LNK2 hardware supports a different app upgrade path from the original LNK1.
